Abstract
Scientists are increasingly specializing to manage the vast knowledge bases within their domains, making knowledge-sharing strategies essential for scientific progress. Among these strategies, international scientific collaboration has increased markedly. We analyse the role of thematic specialization as one of its drivers in the context of Chagas research, a neglected disease. Since there is a strong research tradition in Latin America on this topic, it is an interesting context to study centre-periphery research dynamics. Using a novel bibliometric database on Chagas research during 1990–2019, we exploit its panel structure in a gravity-type econometric model. The findings show that the degree of specialization and its proximity among partners boost joint publications. Both effects are particularly important for country dyads involving authors from the periphery linked to authors in the centre. This paper is the first empirical study to assess the role of specialization as a driver of international scientific collaboration.

Comparamos el efecto de obstáculos externos y capacidades internas de la firma sobre la innovación y la productividad, en la Patagonia versus resto del país para 2014-2016. Nuestra hipótesis es que el contexto regional incide en dichos efectos. Encontramos que en esa región los obstáculos externos afectan la decisión de inversión en innovación, como sucede a nivel nacional, pero además su intensidad. Las capacidades internas son más bajas que para el resto del país, pero tienen mayor incidencia para alentar la decisión de innovación. Estos hallazgos sugieren que la dimensión regional debe ser parte de la política de innovación.
